Product details
Overview
DG201BAK-E3 from Vishay Siliconix is a quad single-pole single-throw (SPST) analog switch with normally closed (NC) configuration, fabricated in silicon-gate CMOS. It supports ±22 V analog signal range, exhibits 45 Ω typical on-resistance, 120 ns turn-on time, and 1 pC charge injection - enabling precision sample-and-hold and digitally programmable filter applications in industrial test equipment.
For engineers reviewing the DG201BAK-E3 datasheet, DG201BAK-E3 pinout, DG201BAK-E3 application, or DG201BAK-E3 equivalent, key selection criteria include its bi-directional analog switching capability, low leakage (±20 pA), RoHS-compliant 16-pin plastic DIP package, and compatibility with TTL/CMOS logic levels across –40 °C to +85 °C operation.
Technical Context
The DG201BAK-E3 implements four independent NC analog switches using Vishay's proprietary silicon-gate CMOS process, delivering lower RDS(on), reduced leakage, and faster switching versus legacy DG201A. Each channel supports true bi-directional signal flow when on and blocks signals beyond supply rails when off.
Its improved charge injection compensation minimizes transients during switching, while an epitaxial layer prevents latch-up. The device operates from dual supplies (±4.5 V to ±22 V) or single supply (+4.5 V to +25 V), with logic thresholds fixed at ≤0.8 V (low) and ≥2.4 V (high).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (dual supply); enables full-range signal routing without clipping in ±15 V systems |
| RDS(on) | 45 Ω typical (V+ = 15 V, V− = −15 V); ensures minimal signal attenuation and gain error in precision paths |
| tON | 120 ns typical; supports high-speed multiplexing up to ~1 MHz without significant settling delay |
| Charge Injection | 1 pC typical; limits voltage glitch in sample-and-hold capacitors to sub-mV levels |
| ID(on) | 20 pA max; preserves DC accuracy in high-impedance sensor or amplifier feedback networks |
| Off Isolation | 90 dB at 100 kHz; suppresses crosstalk between active and inactive channels in multi-channel systems |
| Supply Range | ±4.5 V to ±22 V continuous; accommodates wide industrial and instrumentation supply architectures |
Pinout & Package
Package: 16-pin plastic DIP (JEDEC MS-012), 0.300-inch wide body, through-hole mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 5, 6, 12, 13 | S1–S4 (sources) | Analog input terminals for NC switches; connected to Dx when INx = 0 |
| 7, 8, 11, 10 | D1–D4 (drains) | Analog output terminals; conduct to Sx only when corresponding INx = 0 |
| 9 | V− | Negative supply rail; must be referenced for analog signal clamping and bias |
| 14 | V+ | Positive supply rail; defines upper analog voltage limit and powers internal logic |
| 15 | GND | Logic ground reference; separate from analog ground in mixed-signal layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG201A (Analog Devices) | Same 16-pin DIP, NC topology, but higher RDS(on) (60 Ω typ), slower tON (200 ns), and no RoHS-compliant variant listed in current datasheet | Less suitable for high-speed or low-leakage precision sampling where DG201BAK-E3's 45 Ω and 1 pC are critical | Select DG201BAK-E3 when RoHS compliance, lower on-resistance, or faster switching is required |
| MAX301 (Maxim Integrated) | Quad NC switch in 16-pin SOIC; RDS(on) = 35 Ω typ, but only rated to ±15 V analog range and lacks extended temp grade (-40 °C to +85 °C only) | Not recommended for ±22 V signal handling or industrial environments requiring full -40 °C to +85 °C validation | Prefer DG201BAK-E3 for designs needing ±22 V tolerance and guaranteed performance across full temperature range |
Compared with ADG201A and MAX301, DG201BAK-E3 delivers superior analog signal integrity (lower RDS(on), lower Q, wider voltage range) in a RoHS-compliant through-hole package, making it optimal for precision industrial instrumentation where layout flexibility and thermal robustness are prioritized over surface-mount density.

FAQ
What is the maximum analog signal voltage supported by DG201BAK-E3?
DG201BAK-E3 supports analog signals up to ±22 V when operated within its absolute maximum ratings. Under normal continuous operation, the guaranteed analog signal range is ±15 V with dual ±15 V supplies, as specified in the electrical characteristics table. Exceeding V+ or V− by more than 2 V triggers internal clamping diodes, so external limiting is advised for transient overvoltage conditions.
Is DG201BAK-E3 pin-compatible with the older DG201A?
Yes, DG201BAK-E3 is pin-compatible with DG201A and shares identical 16-pin DIP footprint and pinout. However, DG201BAK-E3 offers improved specifications: 45 Ω vs. 60 Ω typical RDS(on), 120 ns vs. 200 ns tON, and 1 pC vs. 5 pC charge injection. No PCB changes are required for drop-in replacement where enhanced performance is beneficial.
Does DG201BAK-E3 support single-supply operation?
Yes, DG201BAK-E3 supports single-supply operation from +4.5 V to +25 V. In this mode, V− is tied to ground, and the analog signal range becomes 0 V to V+, with typical RDS(on) of 90 Ω at V+ = 12 V. Logic thresholds remain unchanged (VINL ≤ 0.8 V, VINH ≥ 2.4 V), preserving compatibility with standard 3.3 V or 5 V digital controllers.
What is the operating temperature range for DG201BAK-E3?
DG201BAK-E3 is rated for operation from –40 °C to +85 °C, as indicated by the "D" suffix in its ordering code. This range is validated per specification tables and applies to all electrical parameters unless otherwise noted. Derating begins above 75 °C, with power dissipation reduced by 6.5 mW/°C.
How does the normally closed (NC) functionality of DG201BAK-E3 benefit system design?
The NC configuration of DG201BAK-E3 ensures analog continuity between Sx and Dx when logic input INx is low (0), and opens the path when INx is high (1). This provides fail-safe behavior: if control logic fails or power is lost, the switch remains closed, preserving signal path integrity - critical in safety-monitoring, sensor backup, or power-loss recovery circuits.
